Spearman correlation analysis depicted that the relative expression levels of EZH2 and RND3 were positively correlated with CA125 of the corresponding endometriosis samples, (r = 0.7817, p < 0.0001) and (r = 0.7793, p < 0.0001), respectively, (Figure 6B). The gene discussed is RND3; the disease is endometriosis.
